Quick overview on how to go about updating the firmware of your D4R-II Receiver to run more channels in CPPM mode. As per the FrSky Website this update will increase the period of D4R-II CPPM channel from 18mS to 27mS.
Keep in mind you would go from 18ms to 27 for more channels, so if you're not using more than say 5 or 6 then don't update since there is no need and you get less latency. This video is pretty old now and if you're in the market for a new RX consider the X4R or XSR since both of these are SBus and as such way lower latency.
I actually had issues with this video where I lost some footage and audio due to a corrupt SD Card. I hope this all still makes sense. Sorry it took so long to get this one done.
